Since the first day I joined a signature campaign I have not received any payments directly to a casino account because the managers don't pay to the casino account but I sted they normally pay to my Bitcoin wallet address which k provide. Actually it will be nice to gamble with signature campaign payments because "Why Not? But the actual truth is that it's not everything that the campaign participants will gamble with their payments, sometimes they add it to their anonymous wallets to increase the asset on their portfolio.
